Abstract

A component control arrangement for transit-type vehicles having a distributed plurality of vehicle components to be monitored and controlled, includes a number of function control modules, each being associated with a specific vehicle function; as for example, wheel-skid, climate-control, and verification systems. The function control modules, each communicate in a multiplex arrangement over a shared data bus and a transceiver arrangement, with a distribution unit. The distribution units have an output configuration allowing connection to a variety of vehicle operating devices including lamps, switches, solenoid valves, and electric motors. The function control modules evaluate status indications originating from the vehicle operating devices and transmitted through the distribution units and a transceiver arrangement. The function control modules utilize the status indications to derive control instructions for the vehicle operating devices based on a predetermined set of vehicle operating and safety parameters.

Description

Die Erfindung betrifft ein Multiplex-System zum Abfragen und Steuern von mehreren Komponenten eines Fahrzeuges gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a multiplex system for querying and controlling a plurality of components of a vehicle according to the preamble of patent claim 1.

Aus der EP-A-00 82 300 ist ein solchen Multiplex-System bekannt, dessen Sender mit Mikrocomputern ausgerüstet ist. Diese dienen aber lediglich zur Erzeugung und zum Lesen von Multiplex-Datenwörtern bzw. Befehls-Telegrammen und führen keine intelligenten Steuer- und Regel-Funktionen aus. Zur Erhöhung der Betriebssicherheit sind in der genannten Entgegenhaltung zwei Mikrocomputer parallel geschaltet. Die ebenfalls aus der genannten Entgegenhaltung bekannte Anzeige- und Tastatureinheit enthält ebenfalls keine eigene Intelligenz und ist auch nicht mit einem eigenem Mikrocomputer ausgerüstet.Such a multiplex system is known from EP-A-00 82 300, the transmitter of which is equipped with microcomputers. However, these are only used to generate and read multiplex data words or command telegrams and do not perform any intelligent control functions. To increase operational safety, two microcomputers are connected in parallel in the cited document. The display and keyboard unit, which is also known from the cited document, likewise does not contain its own intelligence and is also not equipped with its own microcomputer.

Durch die DE-A-24 33 025 ist eine Einrichtung zum Steuern und Kontrollieren von elektrischen Schaltvorgängen in einem Kraftfahrzeug bekannt, bei der in der zentralen Sendeeinheit gewisse logische Verknüpfungen von Komponenten-Ausgangssignalen vorgenommen werden, die als Rückmeldesignale über den Zustand von Schaltern und Lampen des Kraftfahrzeuges zur zentralen Sendeeinheit übertragen werden. Eine weitergehende Verarbeitung von Komponenten-Signalen ist bei der bekannten Einrichtung nicht vorgesehen.From DE-A-24 33 025 a device for controlling and monitoring electrical switching operations in a motor vehicle is known, in which certain logical combinations of component output signals are made in the central transmission unit, which act as feedback signals about the state of switches and lamps of the motor vehicle are transmitted to the central transmission unit. No further processing of component signals is provided in the known device.

Es gibt jedoch eine Reihe von Funktionen, die in zunehmendem Maße ebenfalls über ein Multiplex-Leitungssystem ausgeführt werden können. So kann man z.B. daran denken, die für ein Antiblockiersystem abzufragenden Sensoren und anzusteuernden Magnetventile als Komponenten an die Unterverteilungs-Einrichtung eines Multiplex-Leitungssystems anzuschließen. In Anwendung der Lehre der erwähnten DE-A-24 33 025 könnte man weiter daran denken, die zentrale Sendeeinheit so auszubilden, daß diese die für die Funktion "Antiblockiersystem" erforderlichen Abfragen, Auswertungen und Verknüpfungen unter Verwendung von bereits für den Betrieb des Multiplex-Leitungssystems vorhandenen Schaltkreisen mit übernimmt.However, there are a number of functions that can increasingly be performed via a multiplex line system. So you can e.g. remember to connect the sensors and solenoid valves to be checked for an anti-lock braking system as components to the sub-distribution device of a multiplex line system. In application of the teaching of the aforementioned DE-A-24 33 025, one could also think of designing the central transmission unit in such a way that it performs the queries, evaluations and links required for the "anti-lock braking system" function using already for the operation of the multiplex Existing system with takes over.

Insbesondere in dem Fall, daß man noch weitere spezielle Funktionen, wie z.B. "Klimasteuerung", "Türsteuerung" (z.B. in Omnibussen) oder "Anzeigen und Bedienen" realisieren will, würde die zentrale Sendeeinheit sehr aufwendig und damit störanfällig. Ein Ausfall eines Teiles einer solchen zentralen Sendeeinheit könnte die Arbeitsweise aller realisierten weiteren Funktionen gefährden. Im Falle eines Defektes muß u.U. die ganze Sendeeinheit ausgewechselt werden.Especially in the event that other special functions such as e.g. "Central control", "door control" (e.g. in omnibuses) or "display and operation", the central transmission unit would be very complex and therefore prone to failure. A failure of a part of such a central transmission unit could endanger the functioning of all other functions implemented. In the event of a defect, the whole transmitter unit can be replaced.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Einrichtung der eingangs genannten Art zu schaffen, die mit geringem Aufwand einen weitgehend sicheren Betrieb ermöglicht.The object of the invention is therefore to create a device of the type mentioned at the outset which enables largely safe operation with little effort.

Diese Aufgabe wird durch die im Patentanspruch 1 angegebene Erfindung gelöst. Weiterbildungen und vorteilhafte Ausführungsbeispiele der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by the invention specified in claim 1. Further developments and advantageous exemplary embodiments the invention are specified in the subclaims.

Die Erfindung weist den Vorteil auf, daß mit geringem Aufwand eine Erweiterung oder Reduzierung der Einrichtung durch einfaches Hinzufügen oder Abtrennen von Modulen verschiedener Funktion möglich ist. Es ist von erheblichem Vorteil, daß die Unterverteilungs-Einrichtungen sowie die zentrale Sendeeinheit unabhängig von dem speziellen Aufbau der anschließbaren Module standardisiert ausgeführt werden können. Es ist lediglich ein Standard über die Anschlüsse der zentralen Sendeeinheit und der Unterverteilung-Einrichtungen und über die Übertragungsweise des Multiplex-Leitungssystems und des Datenbus-Systems erforderlich. Bei einer Störung in einer der Baugruppen muß nur das betreffende Modul oder die vergleichsweise einfach aufgebaute zentrale Sendeeinheit ausgewechselt werden. Darüber hinaus ist es möglich, daß die Module mit Programmen für entsprechende programmierbare Rechner versehen werden können und daß bei einer Weiterentwicklung oder Veränderung der Funktionen des betreffenden Moduls lediglich das Programm ausgewechselt werden muß.The invention has the advantage that the device can be expanded or reduced by simply adding or separating modules of different functions with little effort. It is of considerable advantage that the sub-distribution devices and the central transmission unit can be implemented in a standardized manner regardless of the special structure of the connectable modules. All that is required is a standard for the connections of the central transmission unit and the sub-distribution devices and for the way in which the multiplex line system and the data bus system are transmitted. In the event of a malfunction in one of the modules, only the module in question or the comparatively simple central transmission unit must be replaced. In addition, it is possible that the modules can be provided with programs for corresponding programmable computers and that when the functions of the module in question are further developed or changed, only the program has to be replaced.

Die Erfindung wird anhand eines Ausführungsbeispiels, das in der Zeichnung dargestellt ist, näher erläutert.The invention is explained in more detail using an exemplary embodiment which is illustrated in the drawing.

Die Zeichnung zeigt eine als Multiplex-Sender/Empfänger ausgebildete Sendeeinheit 11 eines Kraftfahrzeugs und drei Unterverteilungs-Einrichtungen 17, 23 und 25, wobei die Unterverteilungs-Einrichtungen 17, 23 und 25, über ein Multiplex-Leitungssystem 13 mit der Sendeeinheit 11 verbunden sind. Die Sendeeinheit 11 weist Multiplex-Eingänge und -Ausgänge 12 auf, an die das Multiplex-Leitungssystem 13 angeschlossen ist. Entsprechend weisen die Unterverteilungs-Einrichtungen 17, 23 und 25 Multiplex-Eingänge und -Ausgänge 14, 15 und 16 auf.The drawing shows a transmission unit 11 of a motor vehicle designed as a multiplex transceiver and three sub-distribution devices 17, 23 and 25, the sub-distribution devices 17, 23 and 25 being connected to the transmission unit 11 via a multiplex line system 13. The transmission unit 11 has multiplex inputs and outputs 12 to which the multiplex line system 13 is connected. Correspondingly, the sub-distribution devices 17, 23 and 25 have multiplex inputs and outputs 14, 15 and 16.

An die Unterverteilungs-Einrichtungen 17, 23 und 25 sind jeweils vier Komponenten des Kraftfahrzeugs angeschlossen. Dies sind beispielsweise bei der Unterverteilungs-Einrichtung 17 eine Lampe 18, ein Magnetventil 19, ein Elektromotor 20 und ein Sensor 21. Entsprechend sind an die Eingänge und Ausgänge 22 und 24 der Unterverteilungs-Einrichtungen 23 und 25 je vier weitere Komponenten des Kraftfahrzeugs angeschlossen.Four components of the motor vehicle are connected to the sub-distribution devices 17, 23 and 25. In the sub-distribution device 17, these are, for example, a lamp 18, a solenoid valve 19, an electric motor 20 and a sensor 21. Correspondingly, four further components of the motor vehicle are each connected to the inputs and outputs 22 and 24 of the sub-distribution devices 23 and 25.

Das Multiplex-Leitungssystem 13 wird beispielsweise im Zeitmultiplex- oder im Frequenzmultiplex-Betrieb betrieben. Über das Multiplex-Leitungssystem 13 werden zwischen der Sendeeinheit 11 einerseits und den Unterverteilungs-Einrichtungen 17, 23 und 25 andererseits Ausgangssignale der an die Unterverteilungs-Einrichtungen 17, 23 und 25 angeschlossenen Komponenten sowie Steuersignale für die erwähnten Komponenten ausgetauscht. Es ist z.B. möglich, daß die Komponenten 18, 19, 20, 21, 22 und 24 ständig von der Sendeeinheit 11 abgefragt werden. Es ist aber auch möglich, daß die erwähnten Komponenten von der Sendeeinheit 11 nur zu zuvor bestimmten oder vorbestimmbaren Zeiten abgefragt werden. Dabei ist noch die Verwendung einer Prioritäts-Schaltungseinrichtung möglich, um bestimmte Komponenten häufiger oder bevorzugt abfragen bzw. ansteuern zu können.The multiplex line system 13 is operated, for example, in time-division multiplex or frequency division multiplex operation. Output signals of the components connected to the sub-distribution devices 17, 23 and 25 and control signals for the components mentioned are exchanged between the transmitter unit 11 on the one hand and the sub-distribution devices 17, 23 and 25 via the multiplex line system 13. It is possible, for example, that the components 18, 19, 20, 21, 22 and 24 are continuously queried by the transmitting unit 11. But it is also possible that the components mentioned from the transmitter unit 11 can only be queried at previously determined or predeterminable times. It is also possible to use a priority circuit device in order to be able to query or control certain components more frequently or preferably.

Die von der Sendeeinheit 11 abgefragten Komponenten-Ausgangssignale bzw. die diesen Signalen entsprechenden Datenwörter eines binären Datensystems, sind an Dateneingängen und -ausgängen 10 der Sendeeinheit 11 abgreifbar. Über diese Dateneingänge und -ausgänge 10 erhält die Sendeeinheit 11 ferner Datenwörter oder Signale zugeführt, die zum Steuern bzw. Abfragen der Komponenten bzw. der Unterverteilungs-Einrichtungen 17, 23 und 25 dienen.The component output signals queried by the transmission unit 11 or the data words of a binary data system corresponding to these signals can be tapped at data inputs and outputs 10 of the transmission unit 11. Via these data inputs and outputs 10, the transmitting unit 11 also receives data words or signals which are used to control or query the components or the sub-distribution devices 17, 23 and 25.

Zum Auswerten der von der Sendeeinheit 11 an den Datenausgängen 10 abrufbaren Datenwörter und Signale ist eine Reihe von speziellen, gesondert angeordneten Modulen vorgesehen, die ihrerseits Dateneingänge und -ausgänge aufweisen. Zwischen den Dateneingängen und -ausgängen 10 der Sendeeinheit 11 und den Dateneingängen und -ausgängen 5, 6, 7 und 8 der Module 1, 2, 3 und 4 ist ein Datenbus-System 9 angeordnet, das z.B. in üblicher Weise und nach Art eines Computer-Datenbusses Daten und Signale zwischen den Modulen 1, 2, 3 und 4 einerseits und der Sendeeinheit 11 andererseits auszutauschen erlaubt. Dieser Austausch von Daten und Signalen auf dem Datenbus-System 9 kann z.B. im Multiplex-Betrieb mit Adressen und Quittiersignalen erfolgen.A number of special, separately arranged modules are provided for evaluating the data words and signals that can be called up by the transmitter unit 11 at the data outputs 10, which modules in turn have data inputs and outputs. A data bus system 9 is arranged between the data inputs and outputs 10 of the transmitter unit 11 and the data inputs and outputs 5, 6, 7 and 8 of the modules 1, 2, 3 and 4. Allows data and signals to be exchanged between the modules 1, 2, 3 and 4 on the one hand and the transmitter unit 11 on the other hand in the usual manner and in the manner of a computer data bus. This exchange of data and signals on the data bus system 9 can e.g. in multiplex mode with addresses and acknowledgment signals.

Die gesondert angeordneten Module 1, 2, 3 und 4 erfüllen je eine spezielle Funktion. So ist das Modul 1 dafür vorgesehen, die üblichen Anzeigen eines Kraftfahrzeuges wie z.B. Geschwindigkeit, Motordrehzahl, Betriebsmittel-Verbrauch, Kühlwasser-Temperatur etc. vorzunehmen. Aus den Ausgangssignalen von Komponenten wie Drehzahlmesser, Temperaturfühler etc. berechnet das Modul 1 die erforderlichen anzuzeigenden Werte und gibt diese an ein nicht dargestelltes Anzeigefeld. Das Modul 2 ist dafür vorgesehen, alle Komponenten des Kraftfahrzeugs auf Funktionssicherheit und Betriebszustände hin zu überprüfen und gegebenenfalls entsprechende Fehlersignale zu erzeugen, die über das Modul 1 zur Anzeige gebracht werden können. Das Modul 3 enthält im wesentlichen die Regeleinheit eines Antiblockiersystems. Aus den Ausgangs-Signalen von Sensor-Komponenten werden im Modul 3 in üblicher Weise Regelsignale wie z.B. Geschwindigkeits-, Verzögerungs-, und Schlupfsignale erzeugt. Ferner werden im Modul 3 bestimmte Steuersignale für die ebenfalls als Komponenten an eine Unterverteilungs-Einrichtung angeschlossenen Stellglieder (Magnetventile) der z.B. mit Druckluft betriebenen Bremsanlage des Kraftfahrzeugs erzeugt. Das Modul 4 schließlich enthält für die Funktion "Klimasteuerung" die Rechen- und Schaltungseinrichtung zur Steuerung bzw. Regelung z.B. der Temperatur und der Frischluftzuführung des Passagierraumes des Kraftfahrzeugs. Als abzufragende Komponenten arbeiten z.B. Temperatur-Fühler mit dem Modul 4 zusammen, während die im Modul 4 erzeugten Steuersignale Komponenten wie z.B. Lüftermotoren und Wärmeaggregaten zugeführt werden.The separately arranged modules 1, 2, 3 and 4 each have a special function. For example, module 1 is intended to carry out the usual displays of a motor vehicle, such as, for example, speed, engine speed, operating resource consumption, cooling water temperature, etc. Module 1 calculates the required values to be displayed from the output signals of components such as the tachometer, temperature sensor etc. and outputs them to a display field (not shown). Module 2 is intended to check all components of the motor vehicle for functional reliability and operating states and, if appropriate, to generate corresponding error signals which can be displayed via module 1. Module 3 essentially contains the control unit of an anti-lock braking system. Control signals such as speed, deceleration and slip signals are generated in the usual way in module 3 from the output signals from sensor components. In addition, certain control signals are generated in module 3 for the actuators (solenoid valves) of the brake system of the motor vehicle, which is operated with compressed air, for example, which are also connected as components to a sub-distribution device. Finally, module 4 contains, for the "climate control" function, the computing and switching device for controlling or regulating, for example, the temperature and the fresh air supply to the passenger compartment of the motor vehicle. Work as components to be queried, for example Temperature sensor together with module 4, while the control signals generated in module 4 are supplied to components such as fan motors and heating units.

Die Module 1 und 2 können auch in der Weise zusammenwirken, daß fahrzeuginterne Diagnoseabläufe zur Prüfung der Komponenten etc. vorgenommen werden und daß die entsprechenden Ergebnisse wie z.B. Informationen über Ort und Art von Fehlern vom Modul 1 angezeigt oder zur späteren Abfrage gespeichert werden.Modules 1 and 2 can also work together in such a way that in-vehicle diagnostic procedures for checking the components etc. are carried out and that the corresponding results, e.g. Information about the location and type of errors is displayed by module 1 or saved for later query.

Ein möglicher Ablauf für eine in einem Modul realisierte Funktion wird anhand des Moduls 3 näher erläutert. Das Modul 3 erzeugt adressierte Abfrage-Datenwörter, die über die Datenausgänge 7 des Moduls 3 auf das Datenbus-System 9 gegeben werden. Über das Datenbus-System 9 werden die erwähnten Abfrage-Datenwörter den Dateneingängen 10 der Sendeeinheit 11 zugeführt. Die Sendeeinheit 11 ordnet diesen Abfrage-Datenwörtern des Moduls 3 die betreffenden Komponenten, d.h. die hier abzufragenden Radsensoren zu. Über den Anschluß 12 erhält die Sendeeinheit 11 beispielsweise periodisch alle erforderlichen Sensor-Ausgangssignale zugeführt, die von den entsprechenden Komponenten wie z.B. dem Sensor 21 über die zugeordnete Unterverteilungs-Einrichtung (z.B. 17) und den zugeordneten Multiplex-Anschluß 14 der Unterverteilungs-Einrichtung 17 auf das Multiplex-Leitungssystem 13 gegeben werden. Auf diese Weise werden also die erforderlichen Sensor-Signale dem Modul 3 über die Sendeeinheit 11 in Form von Datenwörtern zugeführt. Es ist auch möglich, daß die Sendeeinheit 11 Speicher zur Speicherung der aufeinanderfolgenden Ausgangssignale der Komponenten enthält. In diesem Fall tauschen die Sendeeinheit und die Unterverteilungs-Einrichtungen ständig Daten und Signale aus, unabhängig davon, ob eine Anfrage seitens eines Moduls vorliegt oder nicht.A possible sequence for a function implemented in a module is explained in more detail using module 3. The module 3 generates addressed query data words which are transferred to the data bus system 9 via the data outputs 7 of the module 3. The query data words mentioned are fed to the data inputs 10 of the transmission unit 11 via the data bus system 9. The transmission unit 11 assigns these query data words of the module 3 the relevant components, i.e. the wheel sensors to be queried here. Via the connection 12, the transmission unit 11 receives, for example, periodically all the necessary sensor output signals which are generated by the corresponding components, e.g. to the sensor 21 via the assigned sub-distribution device (e.g. 17) and the assigned multiplex connection 14 of the sub-distribution device 17 to the multiplex line system 13. In this way, the required sensor signals are supplied to the module 3 via the transmitting unit 11 in the form of data words. It is also possible for the transmission unit 11 to contain memories for storing the successive output signals of the components. In this case, the transmitting unit and the sub-distribution devices constantly exchange data and signals, regardless of whether there is a request from a module or not.

In dem Modul 3 werden die erwähnten Sensor-Signale ausgewertet und bei Blockierneigung des Kraftfahrzeugs zur Erzeugung von Steuersignalen für die in die Bremsanlage des Kraftfahrzeugs eingeschalteten Magnetventile verwertet. Die erwähnten Steuersignale gelangen als Datenwörter über das Datenbus-System 9 zu der Sendeeinheit 11 und schließlich über das Multiplex-Leitungssystem 13 und die Unterverteilungs-Einrichtungen zu den entsprechenden Magnetventil-Komponenten.In module 3, the sensor signals mentioned are evaluated and, if the motor vehicle tends to lock, are used to generate control signals for the solenoid valves switched on in the brake system of the motor vehicle. The control signals mentioned arrive as data words via the data bus system 9 to the transmission unit 11 and finally via the multiplex line system 13 and the sub-distribution devices to the corresponding solenoid valve components.

Man erkennt, daß die Reihe der Module 2 bis 4 beliebig erweitert oder verringert werden kann, ohne daß in der Sendeeinheit 11 eine Änderung vorgenommen werden muß. Die Sendeeinheit 11 kann sich gegebenenfalls auf die bloße Weiterleitung und Ubertragung der erwähnten Datenwörter bzw. Steuersignale und Ausgangssignale beschränken, wenn die Leistungsendstufen für die anzusteuernden Komponenten in den zugeordneten Unterverteilungs-Einrichtungen oder in den Komponenten selbst untergebracht sind.It can be seen that the row of modules 2 to 4 can be expanded or reduced as desired without having to make a change in the transmission unit 11. The transmission unit 11 may be limited to the mere forwarding and transmission of the mentioned data words or control signals and output signals if the power output stages for the components to be controlled are accommodated in the assigned sub-distribution devices or in the components themselves.

Für den Fall, daß ein Modul ein einem programmierbaren Rechner zugeordnetes Programm enthält, ist eine Anpassung des Moduls an geänderte Forderungen bezüglich der betreffenden Funktion durch einfachen Austausch des Programms möglich.In the event that a module contains a program assigned to a programmable computer, it is possible to adapt the module to changed requirements regarding the function concerned by simply exchanging the program.

Bei der Ausbildung der Unterverteilungs-Einrichtungen ist es vorteilhaft, wenn alle Unterverteilungs-Einrichtungen identisch aufgebaut sind. Es ist aber auch möglich, zwei verschiedene Typen von Unterverteilungs-Einrichtungen zu verwenden, von denen der eine Typ nur zum Anschluß von als Sensoren (Radsensoren, Temperaturfühler etc.) ausgebildeten Komponenten dient und der andere Typ zum Anschluß von als Stellglieder, Anzeigeeinheiten und auch Sensoren ausgebildeter Komponenten dient.When designing the sub-distribution devices, it is advantageous if all sub-distribution devices are constructed identically. However, it is also possible to use two different types of sub-distribution devices, one of which is used only for connecting components designed as sensors (wheel sensors, temperature sensors, etc.) and the other type for connecting as actuators, display units and also Sensors of trained components.

Das Multiplex-Leitungssystem 13 kann in beliebiger Weise z.B. sternförmig oder als Ringleitungssystem ausgebildet sein. Entsprechend wird das Datenbus-System 9 an die Anforderungen angepaßt, die hinsichtlich Art, Menge, Priorität und Länge der Datenwörter vorgegeben sind.The multiplex line system 13 can in any way e.g. be star-shaped or as a ring line system. Accordingly, the data bus system 9 is adapted to the requirements that are specified with regard to the type, quantity, priority and length of the data words.

Das Leitungssystem des Multiplex-Leitungssystems kann außer aus elektrischen Leitungen auch aus Signal- und Steuerleitungen anderer Art (optisch, pneumatisch etc.) aufgebaut sein.The line system of the multiplex line system can be constructed not only from electrical lines but also from signal and control lines of another type (optical, pneumatic, etc.).
